Mine is a milk run. I always go to the same places for work. Korea, Okinawa, Guam, and back to Tokyo. It's not bad and you get to see stuff but it can get old.

The NY's party is called Shinnen Kai...or something close to that. All you can eat/drink for 2 hours is a typical setup, then folks go out on their own from there. There are similar things before NYs called Bonnen kai.

Partly, there was also a funny joke involved which makes me grimace when remembering it...my teacher misheard me and thought I said "boki" instead of "bokken" and "boki" just happens to mean erection...go me...so I keep it bokken or bokin as a laugh and use other names for a few sites. But it did originate from martial arts as I used a bokken when training a long time ago.

But NY's parties sound fun...all you can eat...I wouldn't be talking too much I think...
